Inventor: HOZUMI YOSHIO
IPC: G04G15/00
Filed: 1976-10-28
Abstract: 1536001 Electronic alarm timepieces DAINI SEIKOSHA KK 27 Oct 1976 [28 Oct 1975]  44637/76 Heading G3T In an electronic alarm timepiece, having a 24- hour basis digital display and a plurality of memory circuits for memorizing respective alarm times which can be selectively displayed, in response to an output signal from a respective NOR circuit 1, Fig. 1, when a memory circuit Ml, M2 or M3 is reset the segment "g" only of each display device Fig. 2, is energized so that --:-- is displayed rather than 00:00, thereby distinguishing from a normal time indication. To display the contents of M1, an output from NOR1 causes gates 6, 8 to selectively open transmission gates 21-24 thereby to pass a 32Hz drive signal AC 1 directly or via an inverter 20 to a common display electrode 34 and to selected ones of segment electrodes S1 as determined by the outputs of memory Ml which controls AND gates 11, 12. To display actual time of day, outputs from minutes and hours decoders 35, 41 control AND gates 37, 38, 43, 44 to pass 32Hz drive signals to display electrodes S2, S3. When the memories M1, M2, M3 are set to zero, only the segments "g" corresponding to electrodes S2, S3 of the minutes and hours display devices are energized.

Title: Analogue permanent data store - converts signal into variable width track, or resistive track with variable resistivity and is scanned by flow field
Inventor: KNOLL MEINHARD
IPC: G11C27/00
Filed: 1976-10-30
Abstract: The store is electrically read out. A signal present as a function of time is converted into a function of space, represented by variable track width of a homo-genuous material, or by variable resistivity of a resistive track of constant width. The signal is scanned by electric flow field (1) with continuously movable field boundary. It is directed over the resistive track carrying the signal. Continuous movement of the field boundary generates a current-time function containing the signal.

Patent DE-2715892-A1 (DE)
Inventor: EPPERSON RONALD D
IPC: G04G5/00
Filed: 1977-04-09
Abstract: A resettable interval timer in combination with, but functioning independently from a digital watch which provides horological information. The watch operates in two modes; the first mode displaying horological information on the display devices and the second or stopwatch mode displaying interval timing information on the display devices. In the watch mode the user can program which horological information he desires to be continuously displayed on the display devices, either hours, minutes, and seconds, or hours, minutes, and date. By depressing one of the watch push buttons the user can momentarily display month, date, and the A.M. or P.M. horological information on the display devices. A predetermined push button depression sequence can be used to reset the horological information. When a second push button is depressed a predetermined number of times within a defined time interval the watch enters the stopwatch mode. In the stopwatch mode the user can reset the interval timing counters to zero, start the interval timer, stop the interval timer, freeze the interval timing information currently on the display devices (split or lap time), return the counters to the interval timing mode, and finally return the watch to the watch mode.

Title: Internal telephone network with interconnecting service position - extending blocking control criterion to transmission units to reserve automatic traffic working
Inventor: ALBRECHT MANFRED ING GRAD
IPC: H04Q3/62
Filed: 1977-06-30
Abstract: The telecommunications circuit is esp. for internal networks served by an interconnecting service position. The exchange couplings can be established manually or automatically. An individual-selector-working, coupling transmission is provided for the communications not established via the transmission units coupled to the network. This individual transmission can be seized through the service position and reception of direction data, e.g. dialling code, and consequently coupled with appropriate transmission units via input leads by means of selectors. The service position reserves the automatic traffic by extending a blocking control criterium to the transmission units.

Inventor: KMETZ ALLAN R DR
IPC: G04G9/06
Filed: 1977-11-25
Abstract: For the purpose of displaying arbitrary display patterns, periodic control signals are applied in an electrooptic display device which contains a display, which is constructed from display elements arranged in the form of a matrix, and a drive circuit, to the electrodes, which are connected to one another in an electrically conductive fashion by row and column. In this arrangement, a drive signal which is independent of the display pattern to be displayed is applied to each of the n row electrodes, and a further signal is applied to each of the m column electrodes, this further signal being selected from 2<n)<n>1) different signals whose temporal variation depends at each instant on the desired display pattern of the display elements belonging to the relevant column electrode. This mode of operation can be performed using a very low number of electrode terminals and is suitable for the exceptionally contrasty representation of arbitrary display patterns. <IMAGE>
